The function create_graph_from_edges_dataframe in the hana_ml.graph.factory module creates a HANA Graph workspace based on an edge dataframe, with the vertices table created implicitly based on the 'from' and 'to' columns of the edges, and accepts either a hana dataframe or pandas dataframe as input for the edges table.
------
Here is a Python code template based on the provided help doc:

```python
import hana_ml
from hana_ml.dataframe import ConnectionContext
import pandas as pd

# Create a connection to the SAP HANA system
connection_context = ConnectionContext(address='<address>',
                                       port='<port>',
                                       user='<user>',
                                       password='<password>')

# Load edges data from a CSV file into a pandas DataFrame
e_pdf = pd.read_csv('<path_to_csv_file>')

# Create a HANA Graph workspace based on the edges DataFrame
hg = hana_ml.graph.factory.create_graph_from_edges_dataframe(
    connection_context=connection_context,
    edges_df=e_pdf,
    workspace_name="factory_ws",
    edge_source_column="from",
    edge_target_column="to",
    edge_key_column="edge_id",
    drop_exist_tab=True,
    force_tables=True,
    force_workspace=True
)

# Print the created HANA Graph
print(hg)
```

Please replace `<address>`, `<port>`, `<user>`, `<password>`, and `<path_to_csv_file>` with your actual values.
